“…The coexistence of Cu and Cu 2 O in the synthesized material was also confirmed by use of XRD. The peak at 933.8 eV is due to CuO, although it is slightly higher than the reported energy of CuO (933.7 eV) (Wagner et al, 1979), it agrees well with other values reported for CuO surface phase (Wagner et al, 1979;Espinós et al, 2002;Zhu et al, 2004;Wang et al, 2003Wang et al, 2002Xu et al, 1999;Hui et al, 2002;Brookshier et al, 1999;Fernando et al, 2002). The, three peaks of 530.2, 531.6, 533.6 eV observed in the O1s spectrum (Fig.…”

“…The, three peaks of 530.2, 531.6, 533.6 eV observed in the O1s spectrum (Fig. 4C) are consistent with the broad peak of O1s, the peak at 530.2 eV is consistent with O1s of Cu 2 O that have been reported previously, which are in the range of 530.0-530.7 eV (Wagner et al, 1979;Espinós et al, 2002;Zhu et al, 2004;Wang et al, 2003;Wang et al, 2002). O1s in CuO appears at 533.6 eV and the peak at 531.6 eV was assigned to other oxygen components such as OH, H 2 O and species of carbonate on the surface.…”

• We present an effective catalyst for reductive degradation of organic dyes and phenols in water.• Compared with noble metals, Cu/Cu 2 O/ CuO@C particles are more efficient and less expensive • The porous structure provided a large contact area and channels for the pollutions and active site. , infrared spectroscopy and Raman analysis, revealed that it was composed of graphitized carbon with numerous nanoparticles (100 nm in diameter) of Cu/CuO/Cu 2 O that were uniformly distributed on internal and external surfaces of the carbon support. Gallic acid (GA) has been used as both organic ligand and carbon precursor with metal organic frameworks (MOFs) as the sacrificial template and metal oxide precursor in this green synthesis. The material combined the advantages of MOFs and Cu-containing materials, the porous structure provided a large contact area and channels for the pollutions, which results in more rapid catalytic degradation of pollutants and leads to greater efficiency of catalysis. The material gave excellent catalytic performance for organic dyes and phenols. In this study, Cu/Cu 2 O/CuO@C was used as catalytic to reduce 4-NP, which has been usually adopted as a model reaction to check the catalytic ability. Catalytic experiment results show that 4-NP was degraded approximately 3 min by use of 0.04 mg of catalyst and the conversion of pollutants can reach more than 99%. The catalyst exhibited little change in efficacy after being utilized five times.

“…The Cu 2p signal could be deconvoluted into five peaks (Figure 6a). The binding energies at 933.7 and 953.6 eV are attributed to the Cu 2p 3/2 and Cu 2p 1/2 peaks, respectively, which are consistent with those observed in CuO bulk [45]. The satellite peaks are also produced by Cu 2þ and this feature is located at higher binding energy by about 8.2 eV.…”

A simple and efficient two-step hybrid electrochemical-thermal route was developed for the bulk synthesis of CuO nanoparticles using aqueous sodium nitrate electrolyte and Cu electrodes in an undivided cell under galvanostatic mode at room temperature. The influence of electrolyte concentration on the synthesis of CuO nanoparticles was studied at 1.0 A/dm 2 current density. Electrochemically generated precursor was calcined for an hour at different levels of temperature in the range 200-900 C. The calcined samples were characterised by XRD, TG-DTA, XPS, SEM/ EDAX, TEM, FT-IR and UV-Vis spectral methods. The crystallite sizes were estimated and the thermal behaviour of as-prepared compound was examined. Rietveld refinement of X-ray data shows results matching the monoclinic structure with the space group of C2/c (no. 15). The TEM result revealed that the particle sizes were in the order of 30-50 nm diameter and 120-200 nm length. The blue shift was noticed in UV-Vis absorption spectra. All samples of CuO exhibited randomly oriented hexagonal morphology.

“…Thus, PEG 400 acts as a soft template leading to the formation of CuO nanowhiskers having an average size of $8 nm in diameter and length scales larger than 100 nm (figure 4). In addition, they also carried out preparation of CuO nanorods in the presence of nonionic surfactant [29] as follows. About 200 mg of PEG (M w 20,000) and 178.48 mg of CuCl 2 Á 2H 2 O were dissolved in 200 ml of H 2 O, which was stirred with a magnetic stirrer continuously until both the PEG and the CuCl 2 dissolved completely.…”

Nanotechnology can be defined as the science and engineering involved in the design, synthesis and application of materials and devices on the nanometer scale. It is not in itself a single emerging discipline, but rather a meeting of several traditional sciences such as chemistry, physics, materials science, biology and engineering to bring together the required expertise needed to develop these new technologies. The unique properties of nanoscale materials provide benefits in remediation, pollution prevention, and efficient use of resources; however, the greatest contribution to green chemistry is likely to be the new manufacturing strategies available through nanoscience. So, the present review mainly focuses on the synthesis of semiconductor CuO nanomaterials from different starting materials by adopting various routes such as vapor-solid, vapor-liquid-solid, solid-liquid, etc. to reveal the morphological features of the precursor.
